영문 초록

The segregation mode and linkage analysis of gene for resistance to brown planthopper were examined in F₂ generation and F₃ lines derived from the crosses between resistant cultivar, Hwacheongbyeo and four susceptible genetic marker lines. Four-week-old plants were infested with second-to third-instar nymphs of BPH of biotype 1. The insects were distributed evenly with three to four individuals per plant. The reaction of plants was recorded about 28 to 35 days after infestation when the susceptible marker lines were completely killed. The resistance to brown planthopper of Hwacheongbyeo was governed by a single dominant gene and this resistant gene was independent with the marker genes, such as Ig (liguleless, Ⅱ), wh(white hull, Ⅱ), ph⁺(phenol positive reaction, Ⅱ), xa-1(resistance gene to BLB, Ⅱ), drp(dripping-wet leaf, Ⅱ), RC(Brown pericarp, Ⅳ), gh(gold hull, Ⅵ) and gl(glabrous leaf and hul, XII), respectively.
